Including filter system and high-performance PCBs filter.
Polychlorinated biphenyls (PCBs) are industrial chemicals that linger in the environment and can sometimes find their way into water supplies. These compounds were commonly used in older electrical equipment and certain manufacturing processes, and they tend to persist once they reach waterways. In Garnier, homeowners typically hear about PCBs from utility updates, community conversations, or private water testing, since they don’t always show up visibly in tap water but remain a concern because of their persistence.
PCBs usually occur at very low concentrations, so you won’t be able to detect them by sight, smell, or taste. They can enter local water through legacy contamination, disturbed sediments, or runoff that carries pollutants into surface sources. Even when water from Garnier taps looks clear, residents may worry about long-term exposure through cooking, bathing, and everyday household use. That’s why treating water at the point it enters your home gives protection for every faucet, shower, and appliance—not just a single drinking tap.
The most effective single-filter option for whole-house PCB reduction is a high-quality activated carbon system, typically using catalytic carbon or carbon block media engineered for strong adsorption. Because PCBs are hydrophobic organic compounds, they are well suited to being captured by carbon media rather than by basic sediment filters. As Garnier’s water flows through a properly designed carbon bed, polychlorinated biphenyls can adhere to the carbon surface and be reduced before water reaches your plumbing, while also lowering many other similar organic contaminants.
To work reliably in a Garnier home, an activated carbon PCB filter needs sufficient media volume and contact time for your household flow, and it’s common to include a pre-filter to protect the carbon from early clogging. The carbon stage does the primary removal, but it must be sized correctly and serviced on schedule because adsorption capacity will eventually be exhausted. Mr. Pure Water can evaluate your house and recommend a whole-house carbon system matched to your flow and usage so PCBs are treated where water first enters your plumbing.
